FUEL con'rnonron AUTOMOBILES.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed September 7, 1918. Serial No. 253,114.

To all whom it may concern:

Be it known that I, HARRrMoR'roN MACK, of the city of Calgary, in the Province of Alberta, farmer, having invented certain new and useful Improvements in Fuel Controls for Automobiles, do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to improvements in a fuel control for automobiles, more particularly adapted to those cars where the supply of gasolene through the carbureter is induced by an air current. With this type of carbureter it has been found that the gasolene is drawn into the cylinder in such a form that the perfect mixture with air is impossible and the object of my invention is to provide a means of controlling the amount of gasolene that passes through the carbureter using the present needle valve but connected by levers to a control on the steering pillar within the drivers reach, breaking up the fuel with the air current control into very minute particles, causing a more nearly perfect mixture of the gasolene with the air and increasing the efficiency of the engine by doing away with the trouble attendant on imperfect combustion in the cylinders and decreasing the amount of gasolene consumed per mile of car travel.

I attain these results by the device illustrated in the accompanying drawing, in which Figure 1, is a view of the portion of the device affixed to the dash-board showing thestem of the needle valve and the rod connecting the circular head to the control lever on the steering pillar. Fig. 2, is a side view of the steering wheel showing the present control lever and the additional control lever for the fuel supply. Fig. 3, is a view of the bearing box at the lower end of the operating lever showing the method of retaining the lever in place and preventing undue circular motion. Fig. 4, is a side view of the lower bearing box. Fig. 5, is a detail view of the perforated circular head the perforations being used to vary the point of the application of the power as found necessary for increasing or decreasing the amount of thefuel supply according to the atmospheric temperature, load, or other factors. Fig. 6, shows in detail the ends of the rod connecting to the operating lever.

Similar numbers refer to similar parts throughout the several views.

In the automobiles made by the Ford Company a needle valve is provided on the fuel supply line the stem 13 of which valve projects through the dash-board 2 and has rigidly attached to its upper end a circular disk 11, which disk is provided with a series of circular holes 12 so as to give a wide range of adjustment, into any of which holes the end of the connecting rod 10 will lit, the pear shaped end 10 of the connecting rod 10 allowing of the easy placing but prevents displacement due to vibration. The farther end of the connecting rod 10 is substantially of the shape shown at 10 and passes through the end 5 of the lever 5.

The lever 5 is held in place at its lower end by means of a block 6 secured to the dashb0ard 2 by screws 7, the said block having a pro]ection between the end of the lever rod and the dashboard, a cover plate 8 hav- 1 ing shoulders to prevent undue movement 1 of the lever 5 in either direction, the said cover plate being secured to the block 6'by screws or bolts 9.

The operating lever is revolubly mounted at its upper end by means of a bearing box 16 rigidly mounted on the steering pillar 1 at a point slightly below the present lever 4 the end of the said operating lever 5 after passing through the bearing box having its end turned back approximately perpendicularly to the lever 5. A turning movement of the lever 5 operates the stem of the needle valve 13 varying the amount of gasolene supplied to the engine.

Having thus described my invention, what I claim and desire to secure by Letters Patbeing inserted in one of the said holes, 10 ent is means for supporting said levers, and means A motor fuel controlling device comprisfor retaining the rod in any desired posiing a needle Valve having a disk provided tlon, all substantially as described. with holes near its periphery mounted normal to the axis of the valve, a handled rod HARRY MORTON MACK mounted on the steering post, a system of Witnesses: levers removably connected with the said WILFRID J. GRAY, disk and said rod by a bent end of said rod W P. MAJOR.
